Abstract
Un tube de lampe à DEL et un circuit d'attaque qui forment un remplacement direct de tubes fluorescents avec ou sans ballast, qui fonctionnent sur une entrée de courant régulière haute tension c. a., une entrée de courant pulsé haute fréquence ou une entrée à plus basse tension. Le tube est câblé pour recevoir le courant qui provient de deux tiges d'électrode d'une parmi les paires de tiges aux extrémités du tube, qui logent le circuit d'attaque. Le courant d'entrée est converti en c. c. par un circuit redresseur, puis filtré pour supprimer les fréquences indésirables et la tension à l'aide d'un circuit filtre et commandé à l'aide d'un circuit à courant constant abaisseur pour alimenter un réseau de DEL à l'intérieur du tube.
